So I got my car dyno tuned yesterday.
All was good except I was loosing charging above 5500 rpm.
Before 5500 rpm it was around 13.4-13.5 Volts. Then once around 5500 rpm started going down to 11.5 volts.
Tuner said I need to get my alternator fixed and then can do another pull.
He said like I have red here that this is a common problem with these cars and they are over spinning at high rpms. I know the heat kills these alternators too.
My car only has 15K miles on it but I guess I have seen some alternators go sooner than that.
Anyhow I was going to just get a new Ford OM alternator and use the 3.0 metco alt pulley to slow it down a bit. Im still on the stock crank pulley OD.
or just keep the same 2.6 alt pulley with the new alternator.
What are your thoughts?
I don't think I want to do the aftermarket alternators after lots of readings here. Not a guarantee in my opinion.
